Electronic component mounting system and equipment unit management method for electronic component mounting system

An equipment unit management method in an electronic component mounting system for mounting an electronic component on a substrate to manufacture a mounting substrate, which manages an equipment unit used in component mounting operation, the electronic component mounting system comprising:

• an electronic component mounting line configured to execute the component mounting operation for mounting the electronic component;
• a production plan data storage unit configured to store production plan data including at least a type of substrate, a production time, and number of productions for each production lot of the mounting substrate to be produced on the electronic component mounting line for a plurality of the production lots;
• a mounting data storage unit configured to store therein mounting data indicative of a type and number of the electronic components used in the component mounting operation for each type of the substrates;
• a component library data storage unit configured to store therein conformity information indicative of a conformity of an equipment unit loaded in the electronic component mounting device in combination with the electronic component, and the electronic component;
• an inventory data storage unit configured to store therein inventory data indicative of a stock status of the equipment units including at least a part feeder that supplies the electronic components, and a nozzle that adsorbs and holds the electronic components;
• and a necessary unit data creation unit configured to create necessary unit data indicative of a type and number of the equipment units used in the component mounting operation in the new production lot to be newly produced on the basis of the production plan data and the mounting data for each of the production lots,
• wherein new allocation processing of allocating, for the new production lot, the equipment unit necessary for production execution of the new production lot on the basis of the necessary unit data is executed, and unit reservation processing for registering the allocated equipment unit in the inventory data storage unit is conducted.
